Wpf dictionary binding not updating

There is no shortage of information out there on how to speed up the performance of WPF applications, but too often the focus is on the weird stuff instead of the simpler issues.I’m not going to talk about things like writing to to optimize drawing—it’s a topic covered to death elsewhere.

This indicates to the binding that we’re only going to be updating the binding target (the Combo Box’s Items collection in this case).If the binding is setup correctly and the view model implements the interface to provide notifications when the data changes, the changes are automatically reflected in the elements in the view that are bound to it.Correspondingly, an underlying data value in the view model is automatically updated when the user modifies the bound value in the view.I first think that this will be an easy demo to build: I just have to use the x: Static extension as a source in a Binding and tada this is over! On the contrary, I had to put an instance object on which my static property is defined in the resource and use it as the source of the Binding.In the demo project, I have created an object named Repository which defines a static property named “Color”. In general, most ways of assigning a value to the property don’t do change propagation. ) people still want the 4.0 behavior, with no change propagation, if only because it’s cheaper. The bracker are mandatory for it to work and the XAML processor complains something about attached properties which does not exists: just ignore it.
